[. . . ] If you are addressing an element in an Option Board parameter array, you must also write the element index to IND. When writing an Option Board parameter, the task number specifies the write size. The following example demonstrates how to use the parameter process message area to access Option Board parameters: Step 1 Reading an Option Board Parameter: To read Option Board parameter 965 (Unit profile code): First set PNU and then AK as illustrated below. The Option Board will respond with the illustrated values. Table 40 Parameter Processing Message Area-Reading PNU965 Read parameter value task Parameter number 965 Output area [hex] 1 Word offset Function AK Input area [hex] 1 3C5 +0 PNU 3C5 00 +1 IND 00 00 0000 00 0000 +2 PWE 0302 0000 +3 Task success (WORD parameter) response Read value (The unit profile code) Step 2 Reading an Option Board array element: To read Option Board parameter element 915. 3 (Modbus address mapped into PZD3): Set PNU=393h (915 dec), AK=6 and IND=3. 28 Accessing Parameters Table 41 Parameter Processing Message Area-Reading PNU915. 3 Read element value in array task Parameter number 915 Element at index 3 Output area [hex] 6 Word offset Function AK Input area [hex] 4 393 +0 PNU 393 03 +1 IND 03 00 0000 00 0000 +2 Section 4-5 0000 +3 PWE 0000 Task success (WORD element) response Read value (Modbus address mapped into PZD3) Step 3 Changing an Option Board array element: To change Option Board parameter element 915. 3 (Modbus address mapped into PZD3) to 1F01h (Coil data 0): Table 42 Parameter Processing Message Area-Changing PNU915. 3 Change WORD element value in array Write value Parameter number 915 Element at index 3 Output area [hex] 7 Word offset Function AK Input area [hex] 4 393 +0 PNU 393 03 +1 IND 03 00 0000 00 0000 +2 PWE 0000 1F01 +3 Task success (WORD element) response Step 4 Storing changed parameter(s): To store changed parameter(s) in non-volatile memory, write a 1 to Option Board parameter 971: Table 43 Parameter Processing Message Area-Initiating NV Store Change WORD parameter value task Parameter number 971 Output area [hex] 2 Word offset Function AK Input area [hex] 1 3CB +0 PNU 3CB 00 +1 IND 00 00 0000 00 0000 +2 PWE 0000 Write 0001 +3 Task success (WORD parameter) response Step 5 Resetting the Option Board: To reset the Option Board, write a 2 followed by a 1 to Option Board parameter 972: Table 44 Parameter Processing Message Area-Prepare Reset Change WORD parameter value task Parameter number 972 Output area [hex] 2 Word offset Function AK Input area [hex] 1 3CC +0 PNU 3CC 00 +1 IND 00 00 0000 00 0000 +2 PWE 0000 Write 0002 +3 Task success (WORD parameter) response Without changing AK or PNU, set PWE=1 29 Accessing Parameters Table 45 Parameter Processing Message Area-Initiate Reset Change WORD parameter value task Parameter number 972 Output area [hex] 2 Word offset Function AK Input area [hex] 7 3CC +0 PNU 3CC 00 +1 IND 00 00 0000 00 0000 +2 Section 4-5 Write 0001 +3 PWE 0011 Task failed (Parameter) response Error: Not allowed due to operating state The Option Board correctly executes the task and resets before responding. After the PROFIBUS master has re-connected, the Option Board tries to execute the task a second time. The task fails because parameter 972 may only be set to 1 if the current value is 2. 4-5-1-2 Accessing Inverter Parameters When you address Inverter parameters, IND is used to select the parameter group. Table 46 IND Values and Parameter Groups for Parameter Processing Parameter A@ IND 10h 15h PNU represents the parameter number in that group. To address P160 for example set IND=10h (PNote It is important to use array tasks (6, 7 or 8) when accessing Inverter parameters. IND is only interpreted if the Option Board executes an array task. The following example demonstrates how to use the parameter process message area to access Inverter Parameters: Step 1 Reading an Inverter parameter: To read Inverter parameter P180 (PROFIBUS node address): Table 47 Parameter Processing Message Area-Reading P180 Read element value in array task Parameter number 180 Parameter group P@ Output area [hex] 6 Word offset Function AK Input area [hex] 4 0B4 +0 PNU 0B4 10 +1 IND 10 00 0000 00 0000 +2 PWE 0003 0000 +3 Task success (WORD element) response Read value: PROFIBUS node address Step 2 Changing an Inverter parameter: To change Inverter parameter A001 (Frequency source) to 3 (Modbus): 30 Accessing Parameters Table 48 Parameter Processing Message Area-Changing A001 Change WORD element value in array task Parameter number 1 Parameter group A Output area [hex] 7 Word offset Function AK Input area [hex] 4 001 +0 PNU 001 01 +1 IND 01 00 0000 00 0000 +2 Section 4-5 Write 0003 +3 PWE 0000 Task success (WORD element) response Step 3 Reading an Inverter parameter (DWORD): To read Inverter parameter F002 (Acceleration time 1): Table 49 Parameter Processing Message Area-Reading F002 Read element value in array task Parameter number 2 Parameter group F Output area [hex] 6 Word offset Function AK Input area [hex] 5 002 +0 PNU 002 06 +1 IND 06 00 0000 00 0000 +2 PWE 03E8 0000 +3 Task success (DWORD element) response Read value: Acceleration time = 000003E8h = 1000 = 10. 00 sec Step 4 Changing an Inverter parameter (DWORD): To change Inverter parameter F002 (Acceleration time 1) to 3. 00 sec: Table 50 Parameter Processing Message Area-Changing F002 Write value: 3. 00 sec = 300 = 0000012Ch Change DWORD element value in array Parameter number 2 Parameter group F@ Output area [hex] 8 Word offset Function AK Input area [hex] 5 002 +0 PNU 002 06 +1 IND 06 00 0000 00 0000 +2 PWE 0000 012C +3 Task success (DWORD element) response !Caution Do not access Inverter parameters while the Inverter is being re-initialized (Refer to the MX2-A@ Inverter manual section 6-3). Accessing parameters during a re-initialization will cause the Inverter to go into an undefined state. 4-5-2 PROFIdrive DP-V1 Parameter Channel 3G3AX-MX2-PRT-E Option Board provides Parameter Access in accordance with the PROFIdrive V4 profile definition. Access is only supported on DP-V1 Class 2 slot 0, index 47. You will therefore have to ensure that all MSAC2_Initialize, MSAC2_Write, MSAC2_Read and MSAC2_Abort messages make use of slot 0, index 47. Note The OMRON web-site (http://industrial. omron. eu) provides function blocks that automate parameter access when using the CJ1W-PRM21 / CS1WPRM21 version 3. 0 or newer. These function blocks automate the DP-V1 Class 2 related commands to the PROFIBUS master as well as the DP-V1 parameter channel request and response formats. You can skip this section if you are using these function blocks. 31 Accessing Parameters !Caution Section 4-5 Do not access Inverter parameters while the Inverter is being re-initialized (Refer to the MX2-A@ Inverter manual section 6-3). Accessing parameters during a re-initialization will cause the Inverter to go into an undefined state. 4-5-2-1 Opening and Closing a DP-V1 Channel Before the PROFIBUS master can exchange information with the Option Board, the PROFIBUS master has to open a DP-V1 Class 2 (MSAC2) channel to the Option Board. Please consult the documentation of your PROFIBUS master on how to achieve this. The Option Board only supports one DP-V1 Class 2 (MSAC2) channel.
